What causes bike wobble?
Speed wobble is caused when something, either an inherent misalignment of the frame or components, or an outside force, that causes the wheels to track divergent paths. The frame flexes to allow this to occur until the action is overpowered by the self-correcting forces created by the bike’s steering geometry.
Is a wobbly bike wheel dangerous?
It depends on the reason for them not being true. A lack of equal tension in the spokes could mean weakness in one (or more) of them – and broken spokes are not a good thing to ignore. You can survive one or maybe two for a short while, but eventually the rim could be in danger of collapsing.
What is tank slapper?
A tank slapper is when the handlebars wildly oscillate. They are also called speed wobbles or death wobbles and, as the latter name implies, they can be lethal. They are usually developed at high speed like in the video below. It’s a good reason to always wear proper motorcycle protective gear.
Why is my front bicycle wheel wobbling?
In bikes, speed wobble starts when something causes the front wheel to accelerate to one side. This could be something as simple as the rider shivering on a cold descent, the rider sneezing, a gust of wind, a bump in the road, or perhaps even a wheel that’s not quite true.
What should I do if my bicycle wheel wobbles?
This type of wobble can make braking uneven and create the potential for wheel breakage. To fix an unevenly tensioned wheel, you must put it through the truing process. Deflate the tire after removing the wheel from the bicycle.
What does speed wobble mean on a bike?
Speed wobble, or shimmy, can be defined as “an oscillation of the bicycle steering assembly at frequencies too high for an effective reaction of the rider.” It’s a phenomenon that’s also seen in motorbikes, skateboards, shopping trolleys, and aeroplane landing gear.
Can a speed wobble lead to a crash?
If you’ve ever suffered from a speed wobble you’ll know that it can be scary – very scary – and it can sometimes lead to a crash. So what can you do to control it?

Why does my car wobble at high speed?
Speed wobbles are a horrifying experience. I’ve only had them a few times, once at 95km/h, and it is not a pleasant experience. Speed wobbles can happen for a variety of reasons including loose spokes, a bad tyre, buckled wheel or a seat that’s too high.

How can I Stop my bike from wobbling?
An easy way to help prevent speed wobbles is by holding onto the handlebars, and keeping a proper distribution of weight throughout your bike. Stay calm! Speed wobbles can come out of nowhere, but stay relaxed. Squeeze your knees together on the top tube. This will help distribute your weight across your bike and provide stability.
What causes a bike steering wheel to wobble?
Surprisingly, no one knows 100% exactly what causes a speed wobble. There are a few theories on what causes a bike to speed wobble. The first theory is that your bikes tires aren’t perfectly aligned. Because the alignment is off the tires are fighting against each other which causes the steering wheel to shake at a certain speed.
